Build: 3435
Mode: Singleplayer and coop (dedicated not tested)

SERVER NAME: n/a
SEED-ID: multiple

If applicable:
MODIFIED PLAYFIELDS: no

Reproducibility: Always
Severity: Major

Type: Save Game

Summary: Save game is corrupted while playing / after exiting

Description: A new game starts and plays normally, but upon exiting, it can be observed that the save game is corrupt. Additionally, an error apparently related to reading/writing the .ply file can be found in the logs (example log from affected system attached). Issue only affects one of the two affected systems available for testing.

Steps to Reproduce:

1. Start new singleplayer game
2. Wait for escape pod to land
3. Exit to menu, then go to Resume Game
4. Observe save game is corrupt
5. Also, open log for session, and observe error with player file

Just checked, and it does say 4.8.4084.0.

 

I did not have any corrupted Save game on my end, neither before Unity upgrade nor after(still don't).
But I have only Win7 and my File version is a different one

 

No idea why this machine is affected, not able to reproduce it on my own system and haven’t seen anyone else mention it (though I’m not sure if that might be due to the relatively small number of testers in Experimental).

Even tried renaming the save game folder so that the game would recreate it in case there was some weird permissions issue, which it did, but the issue still happens (all the files and folders in a normal new game are there, in a freshly created Saves folder, but the game still complains it’s corrupt). Both the affected and unaffected systems are on the Windows 10 21H1 update.

 

After swapping save files between the two systems (and renaming the .ply file as appropriate for the different Steam IDs), I’ve a couple of extra data points:

• Save games started on the affected system also appear corrupt on the unaffected system.
• Save games started on the unaffected system do not initially appear corrupt when resuming on the affected system, but after loading the game and exiting to the menu, the save is corrupted.

 

Seems to point towards an Issue with @elmo 's Engine... any background update running yesterday?
I looked up issues with .NET and found this - > https://thetechyinfo.com/fix-net-framework-issue/
in which NVIDIA is named too.

If life is not entertaining enough have issues with a Computer and all hell breaks loose

 

That issue causes system performance issues, though, and not any issues with .NET functionality. It doesn’t look like it’s related to this issue.

 

Well than thats off the table..
Was my kind of "Schuss ins Blaue"(stab in the dark)

 

Just tried a complete reinstall (with fresh EGS Steam folder), and that made no difference either. Stumped with this one, can’t think of anything else to try.

 

Just edited post to confirm that coop is also affected.

 

More testing: replaced the .ply file in the corrupted save game with a copy from my own (uncorrupted) version of the save game and started it on the unaffected system.

The game was playable, and all structures were present, so it appears that it’s only the .ply file that gets corrupted on the affected system.

 

I am getting a CoQ when I exit the game and go back to the main menu.
It has happened both times I exited my survival game.
The save has loaded when I came back to it, but this may be related.

 

Might be worth reporting that as it’s own bug so that it doesn’t get lost in this thread. The exceptions in the log look different, so I think that’s probably an unrelated issue.

 

Great, thanks

 

Thank you Pantera, can't wait to get playing again.

 

just tried this on new game and it is working fine and all other games started that were showing as corrupt are now okay. Thank you very much and I'll get back to playing properly after dinner.
